Most ultrabooks are rubbish. Or too expensive. Had a thought about a new 13" MacBook pro. With an i7 upgrade and 16gb of RAM, it should do nicely. Until I checked the prices. A new 13" Retina MacBook Pro, with the spec I want comes out just shy of £1700 in the UK.
In the US the same thing is approximately, $2000. This equates to £1236 at today's exchange rate, an effective premium/tax/rip-off of £440+ for living in the UK.
As long as I can tolerate an American keyboard (and have £1236 going spare), maybe I'll buy one when I visit the US in January.
